Virtual mirrors are a little different. They are designed to let users see what they would look like wearing products that they might want to buy. Some examples are earrings or other jewelry, lipstick and eyeglasses.

These smart mirror applications are gaining popularity among retail businesses, which want to get people into their stores.

A smart mirror is simply an app that turns the screen of a smart phone or other mobile device into a mirror, using its camera function. As users look at the image, the app will make it appear as if they are wearing the product.

Peter Johnson is with FaceCake Marketing Technologies. He said, “Virtual try-on offers people the ability to try on numerous products, many more than they would be able to try on otherwise.”

Recently, Johnson demonstrated how an app called Dangle works. The software program lets store customers try on different earrings without touching a single pair.

Dangle can be used on a computer tablet. It uses the tablet’s camera and the app’s facial recognition technology to make it appear as if the user is wearing earrings.

The digital earrings in the image appear almost real. They move with the user, providing a realistic experience. With Dangle, retailers can show customers all of their earrings in a short period of time — something almost impossible without technology.

There are other good reasons to use the app. Trying-on products with the virtual mirror means there is nothing to damage, lose or at risk of being stolen.

“This is a way to keep inventory secure, while people are making decisions about what they want to wear,” he said.

A makeover for shopping outside of the home

Virtual mirrors work with another product that takes time and effort to try on: makeup.

A company called MemoMi has developed an augmented reality app that lets customers virtually put on makeup. At Neiman Marcus stores, customers can use the app on a mobile device to see how beauty products would look on them.

The MemoMi software also is designed to teach users how to use the products. The app can record a beauty care expert putting makeup on a model, along with notes and spoken directions. The recording can then be shared with others on social media.

Alec Gefrides is with the American technology company Intel. He said the app can help people use products the way experts suggest and allows them to repeat the process at home.

Getting people to shop in stores again

Smart mirror apps are an example of how retail stores are turning to online services inside their stores to attract customers.

Online shoppers already expect experiences that are in some ways interactive, easy to use and involve social media. Online shopping also makes it easy to pay for products.

A virtual mirror app like Dangle, supporters say, will enable stores to offer a huge number of products with many of the benefits of online shopping.

The MemoMi app lets stores collect information about its users. The information can include what products customers like, dislike and what they bought in the past. Many shopping websites already do this.

Stores hope that by using customer information, salespeople can make better suggestions to customers and sell more goods.

Gefrides believes that stores across the country will improve their businesses as these technologies improve.

“We always hear about the big store closings,” said Gefrides. “But Intel sees technology becoming more important in providing customers with a better experience.”

Instead of gulping your food, try eating more slowly.It may help you drop those unwanted pounds, a new study by Japanese researchers suggests.

与其狼吞虎咽，不如试试悠着点。日本研究人员的一项新研究表明，细嚼慢咽可以帮助减掉多余的体重。

Also helpful: Avoiding after-dinner snacks and eating anything in the two hours before you go to bed, the researchers said.

研究人员说，此外，杜绝餐后零食且睡前两小时内避免进食也有助于减肥。

The study linked those simple changes to a smaller waist, and lower rates of obesity and overweight.

这项研究表明这些简单的饮食调整有助于缩小腰围，降低肥胖和超重的比例。

Compared with people who gobbled their food, those who ate at a normal speed were 29 percent less likely to be obese.But those who ate slowly were up to 42 percent less likely to be obese.

与那些狼吞虎咽的人相比，以正常速度进食的人肥胖几率要低29%。而细嚼慢咽的人发胖几率更是可以降低42%的比例。

In addition, slow eaters tended to be healthier and to have a healthier lifestyle than those who ate quickly or at a normal speed.

另外，细嚼慢咽的人往往比那些狼吞虎咽及正常进食速度的人有更健康的体魄和生活方式。

This study could not, however, prove that eating speed causes or prevents obesity, only that it appears to be associated, the researchers noted.They were led by Dr. Haruhisa Fukuda from the Department of Health Care Administration and Management at Kyushu University Graduate School of Medical Sciences in Fukuoka, Japan.

Practices that impose some mindfulness and discipline on eating may help with both losing weight and staying healthy, Katz said.He’s also president of the American College of Lifestyle Medicine.

兼任美国生活方式医学学院院长的 David Katz说：“那些在饮食上施加一些专注力和自制力的做法可能有助于减肥和保持健康。”

Slow eating is characteristic of a more mindful approach.Food choice is more conscious, and eating is appreciated for quality rather than just quantity, he said.

慢食会迫使人更专注。他说，人们需要有意识地对食物进行选择，吃东西重在质而非量。

Avoiding food in the hours just before sleep also suggests a more thoughtful approach to diet that involves some reasonable constraints, Katz said.

Katz说：“在睡觉前的几个小时里避免进食，其实就是对摄入的合理限制，这也暗合了自控的饮食方式。”

The research team’s findings came from analysis of health insurance data on nearly 60,000 Japanese residents with diabetes who had made insurance claims and had regular checkups between 2008 and 2013.

该研究小组的调查结果来自对近6万名糖尿病患者的健康保险数据分析，这些人曾在2008年至2013年间进行过保险索赔，并定期进行体检。

The checkups included weight and waist size measurements and the results of blood, urine and liver function tests.Participants also were asked about their lifestyle, including eating and sleep habits and alcohol and tobacco use.

检查包括体重和腰围尺寸的测量，以及血液、尿液和肝功能测试的结果。参与者还被问及他们的生活方式，包括饮食、睡眠习惯、以及烟酒的摄入。

At the start of the study, more than 22,000 people routinely ate quickly, while nearly 33,500 ate at a normal speed and almost 4,200 ate more slowly.

在研究开始时，超过22,000人经常吃得很快，而近33,500人以正常速度进食，近4,200人吃得慢。

Although reductions in waist size — a sign of a potentially harmful midriff bulge — were small, they were greater among those who ate slowly or at normal speed, the study found.

研究发现，虽然腰围变小——这是潜在有害的腹部隆起的迹象——但在那些慢速或正常速度的人群中，腰围却更小。

Snacking after dinner and eating within two hours of going to sleep also were linked to changes in weight.Skipping breakfast was not.

体重变化与晚餐后吃零食，睡前两小时内吃东西息息相关。与不吃早餐无关。

Previous research has linked eating quickly to impaired glucose tolerance and insulin resistance.The study suggested that this might be because fast eaters consume more food before feeling full.

先前的研究表明，快速进食会导致葡萄糖耐受不良和胰岛素抵抗。研究表明，这可能是因为吃快餐的人在吃饱之前会消耗更多的食物。

Slow eaters, however, become aware of feeling full before they’ve consumed too much.

然而，慢食者在吃得太多之前就会意识到饱了。

Slow eating has its pros and a few cons, said Samantha Heller, a senior clinical nutritionist at New York University Medical Center in New York City.

纽约大学医学中心的资深临床营养师Samantha Heller说：“慢食既有优点也有缺点。”

On the one hand, slow eating gives our bodies time to register a sense of satisfaction and fullness, so we tend to eat less, she said.

她说，一方面，慢食让身体有时间来反应这种满足感和饱腹感，所以往往能让我们吃得更少。

We are more likely to savor the taste, texture, subtle flavors and mouth feel of foods, said Heller, who was not involved with the study.”Research suggests that slow eaters consume fewer calories, have increased feelings of fullness and a decreased sense of hunger.”

On the other hand, the longer some people linger with food in front of them, the more they eat, she said.

她说，另一方面，有些人在食物面前逗留的时间越长，他们吃的就越多。

That said, speed eating appears to be far more deleterious, Heller said.”People who speed eat, as many of us do, scarf down far more calories than they need.”

“那就是说，吃速食似乎更有害，”海勒说。“像我们很多人一样，快速进食的人摄入的卡路里远远超过他们所需要的卡路里。”

Eating quickly has been associated with a higher risk for obesity, cardiovascular disease and metabolic syndrome, Heller said.

海勒说，快速进食与肥胖、心血管疾病和代谢综合征的高风险有关。

In many European countries, slow eating is a way of life, she said.”In America, speed eating takes the lead.Thus, we need to encourage a cultural shift to adopting an approach of slower eating and a true enjoyment of food.”

You might not think that mathematicians have anything particularly relevant to say about your love life. But you’d be wrong–if we’re talking about James Murray, a mathematician at the University of Washington in Seattle who teamed up with Psychologist John Gottman to explore the rocky road of romance. Here’s what the two did. They videotaped hundreds of volunteer couples discussing such things as sex and money. You know–the sorts of things on which everybody always agrees, Learn Englishright?

Then they broke down behavioral responses to these high-pressure discussions into recognizable groups, such as whether partner A can be persuaded by partner B, or whether partner A takes offense when partner B makes a cutting remark. A set of equations was drawn up that represented the interactions of these different factors in mathematical form, leading to…Ding!…a prediction as to whether this marriage would last.

Sound like a stretch? Think you can’t possibly tell that much about a couple from a single interview and some calculations? Four years later Murray and Gottman did a follow-up to see whether the equation had made the right prediction. It sure had–their Mathematical Marriage Predictor was right an astonishing ninety-four percent of the time. Some conspicuous findings included the fact that, in marriages that lasted, laughing occurred five times more frequently than in couples destined for break-up. The team also found that the one behavior that most consistently predicted divorce was the appearance of a contemptuous or mocking facial expression on one partner’s face when the other one spoke. According to the Mathematical Marriage Predictor, it’s “roll your eyes and say goodbyes.”

Once there were two mice. They were friends. One mouse lived in the country; the other mouse lived in the city. After many years the Country mouse saw the City mouse; he said, “Do come and see me at my house in the country.” So the City mouse went. The City mouse said, “This food is not good, and your house is not good. Why do you live in a hole in the field? You should come and live in the city. You would live in a nice house made of stone. You would have nice food to eat. You must come and see me at my house in the city.” The Country mouse went to the house of the City mouse. It was a very good house. Nice food was set ready for them to eat. But just as they began to eat they heard a great noise. The City mouse cried, ” Run! Run! The cat is coming!” They ran away quickly and hid. After some time they came out. When they came out, the Country mouse said, “I do not like living in the city. I like living in my hole in the field. For it is nicer to be poor and happy, than to be rich and afraid.”

Dave: Greg, greg. Where in the world are you? Hey, man. I’m in hot water, and it’s all your fault! I thought you said Cindy was single and available!! Man, were you wrong!! You should have told me that your sis had just broken up with a seven-foot gorilla named Butch. I mean the guy is huge, and he caught me dropping her at her place, and he nearly strangled me before I could get in my car. And the guy’s dog. You might have warned me about his vicious beast dog. The thing nearly ripped off my arm.

Well, once I peeled out of the drive way, the maniac started chasing me in his monster truck and nearly ran me off the road. And man, you could have told me that your car didn’t have much gas ’cause it ran out in the middle of this dark parking lot, and I’m now hiding in the men’s room of the gas station. Now, pick up the phone . . . pick it up , . . . Oh, no I can hear the guy outside and . . . hey, and your phone is going dead . . . Ah, man . . . you might have told me that this thing couldn’t hold a charge . . . Ah man . . . I should have stayed home and done the laundry . . . I shouldn’t have listened to your wacky idea of going out tonight . . . Greg, Greg? Where are you?

Every now and then, someone tries to make a case for objective beauty – the notion that there is a quasi-scientific way to judge whether something is beautiful or not. 时不时地，总有些人要纠结什么是客观的美，他们觉得能找到一种准确而科学的方法来界定一个东西到底美不美。

They poorly analyze survey data. In the end, all this so-called objectivity simply serves what they themselves want to express. 这些人总是潦草地分析一堆调研数据，而最终，这种所谓的客观只不过是鼓吹他们自己想表达的那些东西。

Beauty is subjective. Period. 美是主观的，这才是不变的真理。

We each dictate what it is, how it is, and why it is. 对于“美”是什么、如何是、为什么是，我们每个人都有不同的观点。

We assign degrees of beauty to those around us according to preconceived parameters. 我们总是在心里带着自己的标准去衡量身边的人漂不漂亮。

They coincide with what we value in life. 而这些标准其实都反映了我们自己的价值观。

They bounce off of our belief systems, our concepts of good and bad, right and wrong, and some, of righteous or sinful. 它们与我们的信仰、善恶观、是非观、道德观是息息相关的。

A guy’s heart is broken by a beautiful woman with light brown hair and hazel eyes. 一位男子被一名褐发碧眼的美丽女人伤透了心。

It forever alters his experience of those properties on a woman. 于是这个女人的这些特点给他的感觉就永远不再一样了。

A man’s life is saved in the jungle by a woman with corncobs on her head and a plate in her lip. 另一个男人在丛林里被一名女子救了一命，而这名女子头上顶着玉米棒子、嘴唇上串着唇盘。

She is kind, caring, nurturing, and loving. 她很善良、很会照顾人、很有爱心。

He will forever see such women through new eyes. His inner eyes have opened to reveal beauty where once he was blind to it. 于是这名男子看这名女子的眼光从此不一样了。他的心看见了他眼镜看不见的美丽。

I’m really tired of seeing all those dispute about beauty online. 我对网上那些关于美丽与否的争论真的感到很累。

I hope my words can bring you all some inner peace if you need it. 希望我的这些话能帮那些有需要的人找到内心的宁静。

Phil: No I only understand English. China was an eye-opener. It’s a very old culture, but there’s not many new, there’s not many old things around in China, through wars, through the cultural revolution, a lot of stuff’s been burnt, a lot of stuff just’s been knocked down. One of the few old things that is there is the Great Wall of China. It’s very famous this wall, very big. They are doing some efforts to try and build the wall up again, but when I was there, I believe it was August 2002 it was still mostly old stuff.

Todd: Yeah, what else did you see in China?

Phil: Ah, I went to Xian and I saw the Terra-cotta warriors. Terra-cotta warriors were discovered shortly after Mao died in the late 70’s by a farmer who was digging a well, and he was digging this well and he found all these stone warriors, literally hundreds of them, and it’s a national treasure now.

Todd: Wow! That’s fascinating.

Phil: Yeah, it’s really an impressive thing to see. Those are the two really old man-made things that I saw in China.

Todd: Was there anything else that was really spectacular?

Phil: The Three Gorges tour was really good. Sadly they are all under water now because of the dam project, but I was able to go shortly before it was flooded and really, really enjoyed it. Saw a lot of beautiful things. Surprisingly enough the water was a lot cleaner than I thought and I actually went swimming in it.

Todd: Oh, cool.

Phil: Yeah, for, this is the Yangzhe River in China and if you’ve ever seen the Yangzhe, most parts of it, you certainly wouldn’t want to swim in it, but these parts were pristine.

Learn Vocabulary from the lesson

eye-opener

China was an eye-opener.

An ‘eye-opener’ is a surprising or shocking experience. The phrase refers to when you open your eyes really wide if you are surprised. Notice the following:

Living with him was an eye-opener to his real personality.

Although the vacation was relaxing, it was also an eye-opener.

knock down

A lot has been knocked down.

To ‘knock something down’ is to destroy it until there is nothing left. This is when construction companies hit a building with a big heavy ball. Notice the following:

My brother knocked down my sand castle.

The office building was almost completely knocked down by the hurricane.

fascinating

Wow! That’s fascinating.

Something that is very interesting is ‘fascinating.’ Notice the following:

This book that I’m reading is absolutely fascinating.

Don’t you think that archaeology is fascinating?

man-made

Those are the two really old man-made things I saw in China.

Something that is ‘man-made’ is not natural and has been built or constructed by humans. Notice the following:

The man-made bridge was very difficult engineering accomplishment.

Is the lake natural or man-made?

pristine

These parts of the Yangtze were pristine.

If a place is ‘pristine’ it is pure, natural and people have not changed it. Notice the following:

The scenery was so pristine that you felt like you were in a painting.

Mari: That is my favorite dish. My favorite hamburger place is right near where I went to university and they have this hamburger called the Danish Burger, and the Danish Burger has blue cheese inside the hamburger, so I love … my favorite dish has to be the Danish Burger.

Ron: Do you like any side things like french fries with your hamburger?

Mari: I love french fries but I know that eating hamburger and french fries is a little bit unhealthy so I always replace the french fries for a salad.

Ron: A salad. OK. What about dessert? What’s your favorite dessert?

Mari: My favorite dessert has to be chocolate cake.

Ron: Chocolate cake. Anything else? Do you like to eat it with anything?

Mari: No, I like chocolate cake by itself. Anything else? I like brownie sundaes, like brownies and choc … brownies with vanilla ice-cream. I guess my favorite dessert is anything chocolaty.

Ron: Sounds good. So before you said you like to eat a salad. What type of salad, what type of vegetables do you like?

Mari: I like all vegetables. I like them cooked or raw but I don’t like raw onions.

Todd: So Meg, we are talking about animals; do you like to go to the zoo, I would like to take a course to learn animals?托德：梅格，我们来谈动物；你喜欢去动物园吗？我想去學習動物。

Meg: I love to go to the zoo.梅格：我喜欢去动物园。

Todd: Okay. So when you go to the zoo, what animals do you like to watch?托德：好。你去动物园的时候，喜欢看什么动物？

Meg: I really like to watch giraffes. Giraffes are so tall and giraffes look really soft and friendly, so I wish that I could touch a giraffe someday.梅格：我喜欢看长颈鹿。长颈鹿很高，而且它们看上去柔软又友好，我希望有一天能触摸长颈鹿。

Todd: Oh, that’s so true. There is a zoo near my house in California, and you can walk up some stairs and then you can feed the giraffes, and their face is the same height as your face, and they look really, really cute. Yeah, giraffes are great.托德：哦，没错。我在加州的房子附近有个动物园，可以走上台阶去喂长颈鹿，它们的脸和你的脸一样高，它们看上去真的非常可爱。长颈鹿非常不错。

Meg: Giraffes are so cute. Maybe someday, I can feed the giraffes.梅格：长颈鹿很可爱。也许有一天我也能喂长颈鹿。

Todd: I like how giraffes look. I love their face. And I also love camels, also because I think camels have a similar face. They look really cool.托德：我喜欢长颈鹿的样子。我喜欢它们的脸。我也喜欢骆驼，因为我认为骆驼和长颈鹿很像。它们看上去非常酷。

Meg: I don’t think camels are very cute.梅格：我认为骆驼并不可爱。

Todd: Really?托德：真的吗？

Meg: Yeah. They’re so hairy. Camels have so much hair that they look ugly.梅格：对。骆驼身上的毛太多了。所以它们看上去很丑。

Todd: Oh really. I like camels. They always look cool and relaxed.托德：哦，是吗？我喜欢骆驼。它们看上去又酷又放松。

Meg: They do look relaxed, but I like giraffes better than camels.梅格：它们的确看上去很放松，不过相比于骆驼，我更喜欢长颈鹿。

Todd: Well, what about llamas? Llamas are kind of like camels and they’re kind of like giraffes. They kind of have the same face. Do you like llamas?托德：那美洲驼呢？美洲驼和骆驼很像，也有点儿像长颈鹿。它们的脸都长得一样。你喜欢美洲驼吗？

Meg: Have you heard about llamas spitting at people before?梅格：你以前听说过美洲驼会向人类吐痰吗？

Todd: No. Actually, I think I heard camels do that but maybe llamas do it, too.托德：没有。我听说过骆驼会向人类吐痰，也许美洲驼也会这样做。

Meg: Hmm, I’m not sure.梅格：嗯，我也不太确定。

Todd: Okay. So what about other animals? What other animals do you like at the zoo?托德：好。那其他动物呢？你还喜欢动物园里的哪些动物？

Meg: I really like the zebras because zebras are black and white with stripes. So the zebra stripes are really cool, and zebras are similar to horses. So sometimes I think I could ride a zebra if I had one.梅格：我非常喜欢斑马，因为斑马有黑白条纹。斑马的条纹非常酷，而且斑马和马很像。有时我会想，如果我有一匹斑马，那我可以骑着它。

Todd: Yeah. That would be cool. Zebras do look pretty cool. Are there any other animals?托德：嗯。那一定很酷。斑马看上去真的很酷。你还有喜欢的动物吗？

Meg: Well, there’s one animal that I‘m afraid of, and that’s a bear.梅格：嗯，有一种我很怕的动物，就是熊。

Todd: Yeah, bears are pretty scary.托德：嗯，熊的确很可怕。

Meg: Bears are really scary and they’re so big with huge teeth and giant claws, and I feel like a bear would eat me if I met it in person.梅格：熊非常可怕，而且它们体型庞大，还有巨大的牙齿和爪子，我认为，如果我遇到熊，它会吃掉我。

Todd: Actually, have you seen a bear in the wild?托德：你有在野外地区看到过熊吗？

Meg: No. I have never seen a bear in the wild, and I really don’t want to.梅格：没有，我从来没在野外看到过熊，而且我也不想看到。

Todd: Well, in California, sometimes you can see bears in the wild, small black bears. And actually, the black bears are not that dangerous.托德：在加州，有时你会在野外看到熊，是那种小黑熊。实际上，黑熊不太危险。

Meg: Really?梅格：真的吗？

Todd: Yeah. I mean, you need to be careful when you see a black bear in the wild, but they almost never attack anybody. So the one animal you must be afraid of though, is the mountain lion. So there are mountain lions also in California, and they are scary.托德：对。如果在野外遇到黑熊，那你要小心，不过它们几乎从来不袭击任何人。有一种动物你一定会害怕，那就是山狮。加州也有山狮，它们非常可怕。

Meg: Hmm, so maybe I should avoid mountain lions, too.梅格：嗯，也许我也应该避开山狮。

Todd: Yeah. If you walk in the wild and you see a mountain lion, maybe it’s too late. You’re already in trouble.托德：对。如果你在野外行走时看到山狮，那避开已经太迟了。你已经有麻烦了。

international-lan.comSarah: So do you think we should sent people to Mars or Moon to spend all this money on space travel?萨拉：你认为我们应该花费大笔金钱把人类送上火星或月球进行太空旅行吗？

John: Well, I think we should. Space travel can give people hope for the future, and space travel can unite people from different countries for a common goal.约翰：我认为应该。太空旅行可以让人类对未来充满希望，也可以用共同的目标让不同国家的人团结起来。

Sarah: But do any countries work together to travel in space?萨拉：可是各国有在太空旅行上展开合作吗？

John: Oh certainly. The International Space station has astronauts from different countries working together. And I think that a joint effort is the best way to do space missions. I think that we could go back to the Moon and learn much more by going there than we can learn if we don’t go there.约翰：哦当然有了。来自不同国家的宇航员在国际空间站一起工作。我认为共同努力是进行太空任务的最佳方法。我们可以回到月球，我认为与不去月球相比，去月球可以学到更多东西。

Sarah: I see what you mean, but I think we could learn more and we could improve more if we can help the people on Earth. Think of everything we could learn from the children that can’t get an education these days. Maybe the next Einstein is a poor little girl who doesn’t have the money to go to school. If we spent more money on school or clean water and vaccines, maybe we could learn more from ourselves than from going to space and going to Mars.萨拉：我明白你的意思，不过我认为帮助地球上的人能使我们学到更多、提高更多。想想我们在无法接受教育的孩子身上了解到的情况。也许下一个爱因斯坦就是没有钱上学的贫穷女孩。如果我们在学校、清洁饮用水和疫苗上投入更多资金，也许相比去太空和去火星，我们可以从自己身上学到更多。

John: I agree with you that more should be spent on education, but we don’t need the next Einstein if were not doing space travel. The problem is what are people with money willing to spend it on. I think that it would be nice if we could have all the rich countries spend money on education for poor people, but if you look at the numbers, the cost of one space mission is much cheaper than the things we spend money on now.约翰：我同意你的观点，我们应该加大对教育的投入，但是如果我们不进行太空旅行，那我们不需要另一个爱因斯坦。问题是富有的人想将钱花在哪里。我认为如果所有富有国家都可以增加教育经费，解决穷人上学问题，那是件好事，但是如果看金额的话，你会发现一次太空任务的费用远低于我们现在在其他事情上的花费。

Sarah: Like what?萨拉：比如哪些花费？

John: Well, the first example that comes to mind is war. One day of war is so expensive for all the governments and the militaries that are involved. One day of war costs more money than one space mission. But war goes on and on for days.约翰：我首先想到的是战争。对所有牵涉战事中的国家政府和军队来说，一日军费非常昂贵。一日军费比太空任务的费用要多得多。但是战争会持续很长时间。

Sarah: Yeah, and years.萨拉：对，可能持续数年。

John: So, if you think about money in terms of … sorry … so the money for a space mission is expensive by itself, but when you compare it to other things it’s actually kind of cheap.约翰：所以，如果你想想那些花费……抱歉，一次太空任务的花费的确很多，但是当和其他花费相比时，你会发现其实太空任务并不昂贵。

Sarah: I see what you’re saying. You’re comparing the cost of space travel to war, but I would compare the cost of space travel to the cost of, for example, getting rid of malaria. I think we could get rid of a terrible disease like malaria for as much as we would spend on a trip to Mars.萨拉：我明白你的观点。你将太空旅行的花费和战争花费相比，但是我会将太空旅行的花费和消除疟疾相比。有去火星旅行的那笔费用，我们可以消除疟疾等可怕的疾病。

John:Getting rid of malaria or going to Mars? Well, of course, I would also choose that we get rid of malaria.约翰：消除疟疾还是去火星？当然我也会选择消除疟疾。
